摘要： An ink stick for a phase change ink jet printer is provided. The ink stick includes a first ink stick body segment having a proximal portion and a distal portion, a second ink stick body segment having a proximal portion and a distal portion, and one or more flexible strand portions. The strand portion is formed integrally with the first ink stick body segment and the second ink stick body segment, and connects the proximal portion of the first ink stick body segment and the proximal portion of the second ink stick body segment. The strand portion flexes to permit variation in the distance between the distal portion of the first ink stick body segment and the distal portion of the second ink stick body segment.

摘要： A printing device has an image receptor adapted to have an image formed thereon. The printing device also includes a transfer roller and a motor. A transfer roller load mechanism moves the transfer roller into contact with the image receptor in response to the motor output. A controller manipulates the motor in conjunction with a feedback signal from a load detector and regulates the load of the transfer roller.

The circuit includes a DC power supply having a pair of output terminals, a current sense transformer having a primary winding and a secondary winding, the primary winding being connected at one end to one output terminal of the DC power supply, an H-bridge driver connected to another end of the primary winding and being connected to leads of a three-phase motor to drive each lead to a voltage obtained from the DC power supply through the primary winding, a regulating circuit for identifying the voltage to which each lead is to be driven and for controlling switches within the H-bridge circuit to drive each lead to an identified voltage, and a single current sense resistor connected to the secondary winding of the current sense transformer, the current sense resistor generating a voltage that corresponds to the current being used to drive the three-phase motor.

摘要： An ink jet printer includes an ink supply system and a printhead with nozzles for ejecting ink drops. The printer determines the average size of the ejected ink drops by comparing the number of ink drops ejected in a predetermined time with the quantity of ink delivered through the printers ink supply system during that time. If the determined average ink drop size does not match predetermined ink drop size criteria, the printer adjusts the activation signals for the ink jet nozzles to alter the ink drop size. A solid ink printer determines the quantity of ink delivered through the ink supply system by counting the number of whole or partial ink sticks that pass a predetermined point in the ink supply system. The counter detects a sensing element formed on an external surface of the ink stick. Exemplary detectors include a mechanical arm, or a thermistor to detect a change in the printer melt plate temperature due to a change in the cross sectional area of an ink stick being melted.
